With clients like Halle Berry and Jessica Chastain, Fiona Stiles is one of the top celebrity makeup artists out there. These are the 9 products she can't live without -- and you shouldn't either

Allover face color Since Stiles lugs around a ton of products when she's working, she prefers to streamline her personal makeup bag. "I like products that do double duty," she says. Her favorite multitasker is Stila Convertible Color, $25. She says that there's a color for everyone -- and she uses it as both a blush and a lipstick.

Seriously. $60 lip balm?! I use Blistex Silk 'n Shine for $4 and it works beautifully. I do see the Ecotools brush set in my local drugstore all the time and always wondered about them. I'll give them a try, since the price is more realistic for me. I'm also curious about the Anastasia brow gel. :)
